If you want modern muscle car performance but don't like the small packaging, Hennessey has the answer with the Goliath 700. Based on the new GMC Sierra, the Goliath adds a 2.9-liter supercharger to the stock 6.2-liter V8, bringing horsepower up to a staggering 700. Like all Hennessey's performance packages, the Goliath isn't just a bolt-on supercharger. A custom HPE crankshaft, hardened pushrods, chassis dyno ECU tune, and a 200-mile road tune are included for a reliable kit that can be driven every day. 100 units will be produced, with each one receiving a numbered engine and dash plaque, embroidered headrests, and exterior badging. For those that need more, the Stage 1 Offroad package nets you a heavy-duty front bumper, six-inch lift, and 20-inch Hennessey wheels with 35-inch tires.
